Abstract

Since typhoon is a critical meteorological disaster, some advanced countries have developed typhoon damage prediction models. However, although South Korea is vulnerable to typhoons, there is still shortage of study in typhoon damage prediction model reflecting the vulnerability of domestic building and features of disaster. Moreover, many studies have been only focused on the characteristics and typhoon and regional characteristics without various influencing factors. Therefore, the objective of this study is to analyze typhoon damage by path and develop to prediction model for building damage ratio by using multiple regression analysis. This study classifies the building damages by typhoon paths to identify influencing factors then the correlation analysis is conducted between building damage ratio and their factors. In addition, a multiple regression analysis is applied to develop a typhoon damage prediction model. Four categories; typhoon information, geography, construction environment, and socio-economy, are used as the independent variables. The results of this study will be used as fundamental material for the typhoon damage prediction model development of South Korea.

태풍은 인류에 큰 피해를 주는 재난재해로 몇몇 선진국에서는 태풍으로 인한 건축물 피해액 사전예측 모델에 관한 연구가 진행되고 있다. 국내에서도 해외 연구를 토대로 국내에 적용시키는 연구가 진행되었지만, 태풍의 특성이나 크기 등이 차이가 나므로 국내에 적합한 모델이 필요한 실정이다. 또한, 국내의 연구는 태풍의 특성, 지역적 특성만을 고려하여 진행 하였으나, 태풍은 복합재해로서 태풍의 특성, 지리적 특성만이 아닌 태풍의 진로, 건설환경, 등 다양한 요인을 고려하여야한다. 이에 본 연구에서는 국내에 영향을 미친 태풍을 7가지 타입으로 분류하여 건물피해액 영향인자를 도출하고, 회귀분석을 실시하여 태풍 타입별 건물피해율 예측모델을 개발 목적으로 한다. 이는 선진국의 자연재해 예측모델들과 같이 국내의 상황에 맞는 태풍에 따른 피해를 예측하기 위한 모델 개발을 위한 자료로 활용 될 것이다.
